MACHINE FOR MAKING CIGABILLOS AND THE LIKE.

Application filed November 5; 1921. Serial No. 513,173.

To all whom it may concern:

Be it known that I, ADoLr BAnenBonR, a subject of the Queen of theNetherlands, residing at Rotterdam, Netherlands, have invented certainnew and useful Improvements in Machines for Making Cigarillos and thelike, of which the following is a specification.

In the manufacture of cigaril'los machines are employed comprising ahollow casting having a curved top face formlng a rolhng table providedwith a groove or depression for receiving the tobacco and ad acent tosaid groove with a number of perforations. A belt of leather or othersuitable materlal stretched over said .curved top face is passed over aset oftwo rollers arranged the one overthe other and adapted to reciproecate along the table, the belt being likewise provided with perforationsto coact with those in the table. r

The wrapper, i. e. the tobacco-leaf in which the roll of tobacco is tobe wrapped, is placed on the perforated portion of the leather belt andcaused to be held thereon by atmospheric pressure owing to a vacuumbeing set up in ,the hollow castlng. After the tobacco has beendeposited on the leather,

belt vertically above the groove in the rolling table and forcedthereinto together with that portion of the belt by which it is sup-'ported, the rollers over which the belt is passed are moved along thetable whereby the tobacco is lifted out of the. groove and rolled in thewrapper, which has oneof its edges .gummed, whereupon the completecigarillo is discharged. 7

It has already been suggested to employ in combination with a machine ofthe above type a second hollow member or receiver,

and a third hollow member or transporter, these members having aperforated cover and a perforated bottom r spectively and each providedwith means for producing a vacuum therein, the transporter be ng adaptedfor movement between and for alternate cooperation with the rollingtable In such machines the and the receiver. y wrapper isplaced ontheperforated cover of the receiver and subsequently conveyed by .thetransporter to the rolling table,.it being understood that vacuum issuccessively set up in the receiver, .in the transporter and in thehollow casting forming the rolling table.

My present invention has for its object over the receiver the cover iscertain improvements of the last mentioned type of machines and moreparticularly to provide improved means whereby the wrapper whilesupported by the receiver may be automatically gummed and cut so thatfrom" the moment an attendant has placed a wrapper on the ;rece1ver nofurther manual op-v erations are required and the manufacture of thecigarillo is performed throughout automatically. I

With this object in view I provide a frame carrying the transporter, acutting roller and a gumming brush, and I support fthis ordinarilyoffers serious diificulties owing,

amongst others, to the irregular form of the wrapper and to therequirement that the gumlning-brush should be prevented from contactwith the knife. I therefore provide the perforatedcover of the receiverwith an outwardly sloping end portion the extreme edge of which 1snormally at a certain d1s tance above the knife edge. I further hingesaid cover along the side opposite the sloping portion and I providemeans whereby it'is yieldingly held in its normal position,

thelarrangement being such that when the gumrning brush moves in contactwith said sloping portion the, cover .will not yield and theknife edgecannot begummed, but that duringthe movement of the cutting rollerdepressed so as to uncover the knife.

The presence of holes in thewrapper may cause some glue to adhereto theoutwardly sloping end portion of the receiver'cover. In ordernow toprevent the cutting roller from taking up. this glue I provide the framecarrying this roller with an abutment adapted for coaction with aprojection of the hinged receiver cover so that the cover issufficiently depressed when the cutting roller moves over same] I VAnother nconvenience, exper enced m prior constructions is that duringthe transport of the wrapper the gummed edge of the same may curlwherebythe wrapper would not assume the proper position on the roller table. Inorder to overcome this difliculty I propose to provide the transporterwith a movable member having a flat face adapted during the transport ofthe wrapper from the receiver to the rolling table to contact with thegummed edge through its entire length so that said edge sticks to thisface. The said member, which may be termed edge protector, is adapted tobe forced out of contact with the gummed edge of the wrapper after thelatter has been deposited on the rolling table and held thereon byatmospheric pressure so that the gummed edge is prevented from curling.The movement of the edge protector off the wrapper may simply be broughtabout by a push arm secured to the stamper for forcing the tobacco intothe rolling table groove, and a stationary abutment may be provided onthe receiver for returning the edge protector into its originalposition.

The annexed drawing illustrates, by way of example only, an embodimentof my present invention, Figure 1 being a side elevational view thereofshowing some parts in cross section, whereas Figs. 2 and 3 are a sideelevational view, partly in section, and a cross sectional view of thetransporter and of the receiver, respectively.

In viewvof the above statements a brief description will suffice forexplaining the construction and the modus operandi of the illustratedmachine.

The stationary frame 1 serves to support the hollow casting 2, thecurved top of which forms the rolling table. Said top is provided with across groove 3 for receiving the tobacco, and part of the top adjacentto this groove is provided with perforations 4. Stretched over therolling table is a leather belt 5 passed over rollers 6, 7 at the topendof an arm 8, which is pivoted to the frame 1 as at 9. The right hand endof the belt 5 is secured to the hollow casting 2 as at 10, the left handend thereof being connected through a coiled spring 5 to the frame 1 sothat the belt is always stretched. A stamper 11 secured to the end of anarm 12 serves for pressing the tobacco into the groove 3.

The stationary receiver is designated by 13, the transporter by 14, andthese members and also the hollow casting 2 are provided with meanswhereby they may be connected to a vacuum space.

The wrapper for a cigarillo to be formed on the rollingtable is placedon the cover of the receiver 13 whence it is conveyed by the transporter14 to the perforated portion of the rolling table. The transporter 14,which is provided with a nozzle 16 for the connection of a flexiblevacuum pipe, is carried by a frame 15 through links 17, 18 of equallengths and pivoted to the transporter 14 and to the frame 15 in such amanner as to always remain parallel the one with the other. To the link18 is secured an arm 19 carrying an anti-friction roller 20 guided by asuitably curved slot 21 in frame 1. By these means the transporter 14may be moved into its extreme left hand and right hand positions tocoact with the rolling table 2 and with the receiver 13, respectively.

The frame 15 carries a brush 22 adapted during the movement of saidframe 15 to the right to come into contact with a cylinder 23 revolvingin a container 23 partly filled with glue, whereby the brush takes upsome of the glue to spread it out on the right hand side edge portion ofthe wrapper supported by the receiver 13.

A roller 24 mounted on the frame 15 is adapted for coasting with a knifeto be described in further detail hereinafter.

The frame 15 is supported at its left hand end, as at 25, by the arm 8,and at its right hand side, as at 26, by an arm 27. Arm 8 is pivoted toone endof a rod 28 having its other end hinged to a rod 29 pivotallymounted on the frame 1. Said rod 29 car: ries an antifriction roller 30held in contact with a cam 31 by means of a spring 29?...

The arm 27 is pivoted to a bell crank lever 32, 33 pivoted to the frame1 as at 32 and having an antifriction roller 34 cooperating with a cam35.

The arm 12 is secured to an arm 37 pivoted to the frame 1 as at 37- andcarrying an antifriction roller 38 contacting with the periphery of acam 39.

Cams 31, 35 and 39 are keyed on a com mon shaft 40.

The transporter14, see Fig. 2, is. in the I form of a casing having aperforated bottom 41 and lugs 42, 43 for receiving the pins with whichit is pivoted to links 17 18. Mounted on a stud 44 is the edge protector45 having its under face flush with the bottom face of the transporterwhen assuming the position shown. Said edge protector 45 is providedwith a projection 46 and loadedby a coiled spring 47 which is secured toa fixed pin 47 of the transporter and to a pin 47 of the edge protectorso as to hold the latter in the position shown, or in aposition whereinit is turned away from the casing, dependent upon whether the pin 47- isat the left hand side or at the right hand. side of this line passingthrough pivotv 44. and pin 4 K The receiver 13, see Fig. 3, is in theform of a casing having a perforated cover 48, a knife 49 being screwedto the right hand side wall and adapted for coaction with the roller 24(Fig. 1). The cover 48 has an enlarged right hand end portion having anoutwardly sloping face 50, the outer edge of which is normally at somevertical distance, above the cutting edge of knife 49,

Along its left hand edge said cover is hinged.

spring 48 always tends to hold the cover 48 sociated therewith is againmoved to the to the casing by means of a pin 51.

in contact with a fixed stop member 48 in the. position shown. However,when an abutment. 52 of frame 15 (Fig. 1) engages .a roller 53 mountedonalaterally projecting part of cover 48, the latter is depressedagainst the action of spring48. 1

The receiver is further provided with a finger 54 adapted to coactwiththe projection 46, which further cooperates with a .finger 36 on arm12.

The modus operandi of the described arrangement is as follows: I

A wrapper is placed on the receiver cover 48 and cut at its right handside edge by the roller 24 moving over the cutting edge of knife 49,whereupon the brush 22 gums the 7 which periods vacuum is applied to thereceiver 13, the transporter 14 and. the hollow cas1ng2 in the course ofthese operations.

When the roller 24 moves over receiver 13, the cover 48 is depressed bythe coaction of the abutment 52,-and roller 53 so that the roller 24cannot come-into contact. with gum that may be on the sloping face 50.When the abutment 52 releases roller 53, i. e. before the brush 22 hasreached the sloping face, the cover 48 resumes its normal position undertheaction of spring 48, so that said brush is adapted to spread its gumon that portion of the wrapper which is supported by the sloping face50.

After the brush has done its duly, the transporter 14 is placed inproper position on the cover 48 whereby the projection 46 engages thefinger 54 and the edge protector 45 is returned into the position shownin full lines in F ig. 2, so that the bottom face of said protector mayengage the gummed edge portion of the wrapper. At this moment vacuum isapplied in the transporter casing and atmospheric pressure conditionsrestored in the receiver casing whereby the wrapper is forced againstthe bottom face of the transporter.

As soon as the wrapper carrying transporter has assumed its properposition on the rolling table, the Stamper 11 moves down, therebyforcing the tobacco, which has previously been placed on the belt 5vertically above the groove 3, into said groove together with part ofthe belt. At the same time the finger 36. engages the projection 46 soas to impart to the edge protector 45 an angular motion whereby thelatter is'forced off the wrapper. Subsequently atmospheric I1. Inamachine for manufacturing pressure is restored in the transporter casingand vacuum applied to the casting 2, 'so that right for preparing andpickingfupa next;
